Genesis 43:16-18

16Joseph saw that Benjamin was with them. So he said to his servant who took care of his house, ‘Take these men to my house. Kill an animal and prepare it for a meal. These men will eat with me at noon.’

17The servant did as Joseph told him. He took the men to Joseph's house.

18The brothers were frightened when the servant took them to Joseph's house. They thought, ‘He has brought us here because of the money that we found in our bags last time. Someone put it there before we returned home. Now he wants to punish us. He will take us to be his slaves. He will take our donkeys too.’
